One of an entrepreneur’s most important tools is their car. The costs associated with using it also affect the company’s accounting, especially if the car is used frequently for business purposes. 

The Truster app has a section for car information, where you need to enter the vehicle's registration number, the extent of its use for business purposes, and proof of the car’s value.

In this blog post, we focus specifically on the proof of a car’s value, what information it should include and where to easily obtain one.

How to prove the value of your car? 💰

The easiest way to prove a car’s value is to provide the purchase agreement. The agreement is accepted as proof if it is no more than one year old.

If the deed does not exist, or is too old, you can get a new price estimate free of charge from the Online Car Service.

👇 How to get a free price estimate:

  1. Open this link: https://oma.almaajo.fi/auton-hinta-arvio
  2. Fill in the requested information: car registration number and mileage
  3. Sign in or create an account
  4. Take a screenshot of the completed price estimate

Please note that the price estimate must include the registration number of the car, the estimated price and the date on which the estimate was requested. This certificate is attached to the Truster application so that the value of the company car can be taken into account correctly and up-to-date 📲
